Claudia

Claudia is a smart young woman who has been your good friend for many years. You (a young man) find yourself in possession of a strange technological device. You can't figure it out, so you show it to Claudia. She figures it out quickly and determines it's a technological device that can change the body of one person: you. She's always had a fascination with the idea of gender change, and so she decides to change you into a woman. She's kind of a punk and trickster; she's likely to make you juno through hoops to return to your normal male body. She may even transform you into different hybrid creatures, like mermaids, centaurs, or harpies (all female, of course).
